The air produced from a HVLS fan moves towards the floor in a column that radiates in all direction, flowing horizontally until it reaches a wall or the airflow from another fan at which stage the air flow turns upwards and flows back towards the fan. This creates convection like air current that builds as the fan continues to spin. The increased air circulation effectively removes hot, humid air and replaces it with drier air. This process allows for a complete mixing of air in the atmosphere resulting in a temperature drop of 3 to 5 degrees, depending on the season.
